Thanks, Hopefully I will be able to solve the rest ;)

x1= -20 + x5 + x6 x2 = 50 - x5 -x6 x3 = 40 - x6 x4 = 10 - x5 x5 = free variable x6 = free variable -20 + x5 + x6 ≥ 0 50 - x5 - x6 ≥ 0 40 - x6 ≥ 0 10 - x5 ≥ 0 x5 ≥ 0 x6 ≥ 0 Do you mean this?

Here is the pipe flow network. [PLAIN]http://img36.imageshack.us/img36/8287/pipes.png After I have found the 6 inequalities, the assignment asks me to write them as inequalities for x5,x6 or x5 + x6. Then to minimize flow between D and E. I have to use Linear Programming to find the...

Homework Statement I am doing an assignment in my Linear Algebra class. But I don't know how I will go about solving this problem. So the problem is a network of water pipes. I start with a matrix and I get the solution to the system from the RREF matrix. All the flow directions are set, so...

Wow.. I hope you are kidding, if not, I am so sorry ;(:cry:

Also, is there any other method of doing this other than Loop Current method, Node Voltage method and Branch Current method? Can you use something else, like superposition? It doesn't say so I am completely lost as to what exactly I need to calculate things with.

I gave up.. seems I cannot do it. If anybody is capable and kind, and has enough time to do this I wouldn't mind. It would make me super happy! I want to be able to get this assignment.

Hi, thanks for help! But I am stuck as ever. I know I have to redraw and remove RL but I am uncapable of doing so. I must be an idiot that doesn't see it. I also have no idea how to exactly calculate voltage across the terminals RL is connected to. I tried to use superposition and found...

Homework Statement This is in norwegian but hopefully you can understand it. Here is the assignment and circuit: http://img835.imageshack.us/img835/3619/krets.jpg Find the equivalent Thevenin circuit when when RL is the load Homework Equations The Attempt at a Solution I really don't know...
